GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 257,806, dated May 9, 1882. I Application f`11cd`0etohcr20,1881. (Model.)

To all whom it may concern:

A Be it known that I, FREDERICK J. YANDLE,

of Beloit, in the county of Rock and State ot' Wisconsin, have invented new and useful Improvcments in Grain-Binders, of which thet'ollowing is a specification.

f My invention relates particularly to that class of automatic biudingmachines in which oord is used as the binding material, although 'to it may to some extent prove beneficial in certain styles of wire binders; and it consists in the combination, with the knetter or tyingbill and underlying cord-guide ot a holder beneath the cord-guide adapted to receive the ends of the band and carry them along the guide until lthey come in position for the action of the knotter; in the combination, with the knetter, of a holder adapted to move theretoward to render up slack in the knotting opzo erationfand a support betweenV said knetter and holder to resist the lateral thrust ot' theA baud ends and preserve them iu practically uniform relations to the knetter; in the combination, with the.knetter,.underlying cordguide, and holder beneath said cord-guide, of I a cutter moving transversely to sever the cord, held tense between the guide and holder; in the. combina-tion, with the knetter', of an underlying cord-guide, 'a holder beneath said 3o eord-guide,a movable guide and stripper on the other side of the knetter, and a knife attached to said movable guide and stripper in position to be drawn by its movement across the cord between the guide and holder to sever it', and in other combinations and details of construction, hereinafter pointed out.

In the drawings, Figure l is a front elevation of a binding-head embodying myimprovement. Fig. 2 is a top plan view thereof; Fig.

4o 3, a side elevation, illustra-ting the action ot' the holder; Fig. et, a detached view ot the cord-guide, and Fig. 5a detached viewof the movable guide and stripper.

A is the stock ofthe binding-head, and B a knetter, ot' the type known as tying-bills, supported therein. The axis ot' this knetter in the present instanceis shown as horizontal, or substantially so; but itwill beobvious from the ensuing description that it may assume holder,E,composed in this instance of a rotat- 6o' ing notched disk, e, which takes into a springpressed shoe, c', and is intermittngly moved to force the cord into said shoe, andv thereby clamp it. It is desirable that the holder should yield or move up toward the knetter during the tying operation in order to render up slack. Thelengthofthe ends stretched between knot- A ter and holder at the vmoment ot' the initial vmovement ofthe l'ormcr will in such case often be so great as-to cause a very considerable lia- 7o bility toescape from the action ot'said knetterwhen it once commences its revolution, since its surfaces are necessarily, to some extent, cara. shaped. Moreo\'er,wl|cther the holder is movable or stationary, this `tendency usually, to some extent, exists, as there must bcacertain, space at all times betweenl itand the knetter or band-securing device. I therefore arr-ange between theknotterand holdera curveddeectf ing or guiding arm, F, attached tirmly to the 8o stock by a boltor other connection,f, and directed from that side of the cord-receiving space op posed to theknotter inward and downward toward and underneath the latter, and then later- 'ally a short distance outward, as shown. This y85 serves to guide orlead the band ends of the cord into proper position for the initial :action ofthe knetter, and also to resist and correct the sidewise thrust, push, or displacement given them by the latter as they slip over its crown to form 9o the cross or twist in theloop. Upon theframeis mounted another guide-arm, G, havinga guideway, g, which,when the binding-arm is laying `the cord to form the band, rests in front ot' the knetter and cooperates with the other guidein positioniugthe cord. In order that the arm G may subserve other functions,it is pivoted npon the stock and controlled at its heelend in y such manner that after the knot is formed it is swung aside and hears upon the band between the knetter and the sheaf to strip it forcibly from said knotter. A knife, g', is also attached to this guiding and stripping arm G in such position that as it starts on its sidewise movement to strip the knot said knife is brought against the strands stretched between the other cord-guide and the holder and severs them.

In thebinding-head I have chosen for illustration the inner or under jaw of the knetter is the pivoted one. The binding-arm delivers the cord to the holder through the space or opening h behind both cord-guides, and at this time the knetter is stationary, with its jaws in a substantially horizontal position transverse to this opening. When both ends of the cord have been delivered to the holder the disk e of the latter moves one notch in the direction of the arrow, carrying them into the shoe and firmly clamping them. This movement takes the ends stretched between the knetter and j in contact with the upper surface of the underlying lateral extension j" ofthe guide F, completely shutting off the cord ends between the gavel and the holder from escape and causing them to be directed with certainty inte and between the jaws. l Just as the revolution is completed the jaws come together under the force of the cam C and seize the ends. 'lhe stripper-arm is then actuated, and as it swings aside it first draws its knife against the strands stretched ltense between the guide'F and the holder and severs them, t-he guide at this time acting as a stop againstlateral movement of the strands before the knife. As the stripper-arm continues its movement thc loop is g drawn from the knetter and tightened upon 1 the ends held between the jaws ot' the latter,

and finally these ends are wrenched from its grasp and the bound sheat' drops to the ground, when the parts are restored to their initial position for the next binding operation.

I claim-n 1. In combination with the knetter or bandsecuring device, an underlying cord-guide and a holder beneath the cord-guide adapted to receive the ends of the band and carry them along the guide until they come in position for the action of the band-securing device.

2. In combination with the knetter or tyingbill, a holder adapted to move theretoward to render/up slack in the knotting operation and a support between said knetter and holder arranged to resist'the lateral thrust of the band ends'.

3. In combination with the knetter or tyingbill, an underlying cord-guide and a holder beneath said guide adapted to move toward the knetter during the tying operation'to render up slack.

4. In combination with the knetter, underlying eord-guide, and helder beneath said cordguide, a cutter moving transversely between the guide and holder to sever the cord ends.

5. In combination with the knetter, an underl yin gcord-guide, a holder beneath said cordguide, a movable guide and stripper on the other side of the knetter, and a cutter attached to said guide and stripper in position to be drawn by its movement across the cord between the iirst-named guide and holder to sever it.

6. In combination with the tying-bill having pivoted inner jaw, a eordguide formed and arranged as describeth'whereby the nose of the fixed jaw is caused to traverse a part of said guide as it approaches the end ot' its revolution and while the pivoted jaw is open.

7. rIhe cord-guide F, having the outline shown and described, and arranged substantially as set forth.
